ADHESIVE TAPE.

Application filed December 2, 1'928. Serial No. 152,173.'

This invention relates to an antiseptic adhesive tape and has for itsobject to provide, in amanner as hereinafter set forth, a tape of theclass referred to, capable of being handled in an absolutely sanitarymanner when applied. I

A further object of the invention is to provide, in a manner A,ashereinafter set forth, a tape of the class referred to, with. amedicated element and with means to prevent such element from becomingwet, damp or dislodged after the tape has been applied.

A further object of the invention is to provide, in a manner ashereinafter set forth, a tape of the class "referred` to with amedicated element and with means for` protecting such element when thetape is not in use, and further when the tape is in use, the saidV meansacting as a filtering agent which will permit of the passage of air forventilation, but will not permit the passage of water and othersubstances which may p impair the medicated element or that'may infectthe wound or diseased part upon which the medicated element has beenapplied and held in position by such means.

A further object of the invention is to provide, in a mannerashereinafter set forth, a tape of the class referred to, where-l by itcan be made up in rolls or other forms without the surface thereofsticking together and further to retain the medicinal qualities thereofuntil applied.

Further objects of the invention are to provide, in a manner ashereinafter set forth, an antiseptic adhesivetape, which is"comparatively -simple in its construction and arrangement, durable,strong, compact, thoroughly efficient in its use, convenient-ly appliedand comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists ofthe novel and a pair of oppositel cordance with this invention; and withone a of the protecting elements for the medicated element liftedtherefrom.

Figure4 2 isa cross sectional view of an K antiseptic adhesive tape inlaccordance with this invention.

Figure 3 is a cross sectional view of an antiseptic adhesive tape, inaccordance with this invention, and with each of the protecting elementsof the medicated element shifted off the latter. l

Figure 4 is a fragmentary view, in ltop plan, of the medicatedelement-carrier.

An antiseptic adhesive tape, in accordance with this'invention comprisesa medicated element-carrier referred to generally by the reference'character 1 andhereinafter termed a web, -amedicated element referredto generally by the reference character 2,'

disposed protecting elements for t e me icated element and referred togenerally by the reference characters 3, 4.

The web 1 can be of any desirable length and width andit isconstructed'of closely .Woven fabric, such as high class `shirtinmaterial and preferably the web 1 is forme from closely woven lnadras,but it is to be understood that any closely woven fabric,

suitable for the purpose intended, can be 'used to construct ythe web 1.The lower face 5 of the web l is non-adhesive throughout. The upper face6, of the web 1, at a pointadjacent the longitudinal median thereof andeach side edge is provided with an adhesive coating, and the saidcoatings areindicated at 7, 8. The coatings 7 and 8 are spaced from eachother to provide the longitudinal central portion of the upper face 6 ofthe web 1, free of adhesive material and that portion of the upper face6 of the web 1, which is free of adhesive material is indicated at 9 andis of less width thanl the width of the medicated element2. As the lowerface of the web 1, is free of adhesive material and the portion 9 of theupper face of the web 1 free of adhesive material, the said portionsprovide what may be.

'termed a filtering portlon and said filtering portion is waterrepellent, or in other words the said liltering portion will permit ofthe 4passage of air therethrough for ventilation,

but will not permit water to pass there-v through, as well `as notpermitting other substances to pass therethrough which may, impair themedicated element or that may infect the wound or diseased part uponwhich the medicated element is applied. If the web 1 becomes wet, thethreads from which it is constructed will swell whereby they willclosely fit or abut each other at the said filtering portion and preventthe passage of water therethrough., but will not prevent the passage ofair for ventilating purposes.`

The web 1 is saturated with a solution of oxychinolin, sulphonic acidand sodium bicarbonate and after bein, r saturated it is thoroughlydried. rlhe solution is formed fromeightvparts of oxychinolin, liveparts of sulplionic. acid and twenty-one parts of sodium bicarbonate.This makes the web thoroughly antispetic. The adhesive coatings 7 and Sare of the water repellent type.

The medicated element 2 comprises a carrier for a medicament. Thecarrier is formed from any suitable flexible. material, folded ornonfolded, and which is saturated with any suitable medicament. As shownthe medicated element is constructed, from .medicated light gauzematerial, folded to provide a series of interengagmg lengthwiseextending folds 10, 11, 12 and 13 of equal width. The fold 10 has eachmarginal por tion hof its lower face secured to an adhesive coating.When the medicated element 2 is secured to the web 1, the lower face ofthe fold 10 at the longitudinal center thereof is free of any adhesivematerial and that ortion of the lower face of the fold 10, w ich is freeof adhesive material, is indicated at 14. -By this arrangement there isno adhesive substance present which wll'interfcre with the passage ofair to the medicated element, or in other words that portion of thelower face of the fold 10, which opposes the portion 9 of the upper faceof the web 1 is free of adhesive and under such conditions the air canfilter or passv into the the web. The width of the lnedieate medicatedelement 2 for Ventilating purposes, and which permits the secretion froma wound to be disintegrated, thus more readily keeping the wound openand facilitating the healing process.

The medicated-element 2 is of materially less width than the width ofthe web 1 and is preferably m disposed with respect to the upper face 6of the latter, as to be positioned equi-distant from each side ed e ofelement 2 is such that it will extend-upon the inner` marginal portion Yof each' adhesive coating whereby. the major portion of each adhesivecoating is arranged adjacent the side edge of the element 2.

The protecting elements 3, 4 are remov able, and each of which ispreferabl constructed of gauze. Each protecting e ement is of less widththan the 'width of the web and of greater width than the width of the 4medicated element 2. Each protecting element is co-extensive with themedicated element and each has a portion of its width, as indicated at15 removably secured with the web 1, by an adhesive coating, adjacent toa side edge of the medicated element 2. That portion of the protectingelement which is not connected with the web by the adhesive coating isindicated at 16 and is of greater width than the portion 15. The securedportion 15 of the protecting element is spaced from a side edge of theelement 2. Preferably the v outer side edges of the protecting elementsare flush with the side edges of the web 1.

'Ihe portions 10 of the protecting elements, when in protecting positionwith respect to the medicated element 2, are arranged to overlap eachother as shown in Figure 2 and with the portion 16 of one'of theprotecting elements seated on the top of the medicatec element 2. Theportions 16 of the protecting elements, when in protecting position areoppositely disposed with respect to each other and one overlaps theother. The portions 16 ot' the protecting elements permit of the samebeing readily gras ed and removed from the web 1 when it is esired touse the medicated element 2. When the protecting elements are removed,the adhesive coating exposed is utilized to secure the web to the personwhereby the medicated element 2 will e retained in position, owing tothe characteristic possessed by the web 1 it prevents the medicatedelement 2 from becoming wet or damp after having ,been applied, andfurthermore provides for the passage of air to the medicated element 2for the purpose of sanitation. The tape can be handled in a thoroughlysanitary manner as it is unnec essary at any time for the operator tocome in contact with the medicated element 2.

It is thought that the many advantages of an antiseptic adhesive ta e,in accordance with this invention, can e readily understood, andalthough' the preferred embodiment of the invention is as illustratedand described, yet it is to be understood that changes inthe details ofconstruction can be had which will -fall within the scope of theinvention as claimed.
